    Gather all the materials: 8 plastic cups, vermiculite, soil, irradiated tomato seeds, regular tomato seeds, paper towels, labels, a pencil, and water, a watering can a metric ruler and the data chart. Begin by making a mixture of soil and vermiculite, 50% of each. Label each of the 8 plastic cups, 4 with irradiated seeds and 4 with regular seeds. Radioisotopes have a huge and important effect on the technologies that provide us with food, water and good health. Scientists, doctors and even people everywhere have always struggled with food poisoning and food spoilage because of the insects, fungi or bacteria that can cause human disease or .

    The presence of oxygen and temperature greatly effect the amount lost. For example a beet that was electron-irradiated with a dose of 10kGy had a loss of thiamine that "[3] was 65% at room temperature, 24% at ° C, 12% at ° C, and 5% at ° C." Note that the beet was in a sealed can of nitrogen. First group of seeds was irradiated without soaking (dry group); the second one was irradiated after soaking in irrigation water for 24hours (wet seeds group). Both dry and wet groups were irradiated in two replicates. Germination test: After the treatments, irradiated and .

    MDPI is a publisher of peer-reviewed, open access journals since its establishment in Quality of Irradiated Fresh Produce At low dose levels (1 kGy or less), most fresh-cut vegetables show little change in appearance, flavor, color, and texture, although some products can lose firmness. As an example, the appearance of irradi-ated spinach was similar to that of the non-irradiated samples after 14 days storage at 4°C (Figure 1).File Size: KB.
